ADJUSTABLE BINDER..

Specification of Letters Patent. Patented Sept. 6, 1921.

- Application-filed February 1, 1919. Serial in. 274,461.

T 0 all whom it may concern Be it known that I, ALBERT H. DE Von, a citizen of the United States, residing at W'cstfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Adjustable Binders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an adjustable binder suitable for ready attachment to the cloth-plate of a sewing machine. g

The objects of the invention are to provide a simple, economically manufactured binder having a maximum number of adjustments with the fewest parts, and to more certainly prevent unfolding of the binding strip before it reaches the stitching point.

In the preferred form the inventioncomprises a base provided with means for ad: justably securing it to the cloth-plate of a sewing machine. A pair of spaced and relatively inclined guides having in-turned lips for folding and guiding a binding strip are disposed to oneside of the base, said guides having supports movable in channels cut in the upper and lower surfaces of the base.

-These' guides, while capable of individual adjustment, are secured to the base by a single clamp-screw. and opposed to their iii-turned edges is a member having concaved surface forming an edge-gage for the work as well as acting as an additional guide for the binding strip. This member has a support offset from the guides and adjustably secured to the base. The in-turnedfolding lips terminate short of the discharge end of the binder and one of the guides has a vertical flange beyond its folding lip and extending teward the discharge end of the binder to prevent the binding strip from unfolding. llhe inner gage and guide-member has a projection extending beyond the binder which acts as a guide as the work approaches the stitching point.

In the accompanying drawings, Figure 1 is a top plan view of the binder. Fig. 2 is a bottom plan. *Fig. 3 is an end elevation. Fig. 1 is a side elevation. Fig. 5 is a transverse section taken through the guides, and Fig. 6 is a section at right angles to that in Fig. 5. V 1

Referring to the drawings 1 is the base of the binder having the slot 2 through ictween the guides be adjustablysecured to the cloth-plate of the machine by means of clamp-screw 3. Formed in the upper and lower surfaces of the base are the, respective channels 1 and5 (Fig. 6) in which fit the adjustable guide supports 6 and 7. The support 6has a slot 8 therein, and the sup port 7 has an upwardly projecting lug 9 slidable ina slot 10 in the base. A thumbscrew '11" has a stem-portion 12 passing through the slot 8 and threaded into the lug 9, thereby holding the supports 6 and 7 in relat1v ely adjusted position on the base. At one side of the base the supports 6 and 7 carry the respective binder-guides 13 and 1- 1. Theseguides arerelatively inclined as shown in Fig etand at their outer edges have in-turned folding lips 15 of well known form. The lips do not extend along the entire edges of the guides but terminate at a pomt where, due to the inclination of the guides, the work commences to be crowded. To preventthe folded edge of the binding strip from becoming unfolded after it passes the lips 15 the upper guide is provided with a downwardly extending flange 16 beyond the point where the upperlip l5 terminates. The base 1 is provided with a channel 17 on its upper surface in which is slidable a support 18. A clamp-screw 19 has a stem 20 passing through a slot 21 in the support 18 and threaded into the base-1. At one side of the base the support 18 carries. an olf' set gage and guide member 22 which extends-between the guides 13 and 1 1 and terminates in a reduced portion 23 beyond the dischargeend of the binder. The guide-' member 22 has a con-caved surface 24 which is opposite the lips 15. lower surfacesof the part 22 have shallow notches rearwardly of the points 25,-whicl.i allows the discharge ends of the guides 13 and 14 to be brought closer togther, as shown in Fig.4. The shoulders formed at the points 25 also act as steadying and guiding means for the discharge edges of the guides 13 and 1 1 when the latter are extended from the base, as shown in Figs. 1 and 2. e l

In the operation of the device the binding strip is fed'in between the guides 13 and 14: and folded by the lips 15 and concaved surface 241 in a well known manner around the work disposed between the lips 15. Owing to the proximity of the inclined guides 13 which it may The upper and bindin stri a and 14 at the point where the work leaves the binder the folding lips 15 terminate short of this point to allow room for the work and but to prevent any possible unfolding of the turned-in edges of the binding strip the upper guide 13 is pro'vided with the downwardly directed flange 16. The reduced portion 23 aidsin guiding the work to the stitching point after it has left the binder. It will be noted that while the device is simpleand contains few parts, numerous adjustments are possible. By simply loosening the clamp-screw 11 the guides 13 and 14: may be independently or simultaneously adjusted relatively to the base and to the gage and guide member 22. By loosening the set-screw 19' the gage member 22 may be adjusted relatively to the guides 13' and 14 and to the base, and by loosening set-screw '3 the entire binder may be adjusted on-the throat-plate of the machine. Ihe object of allthese adjustments is to vary the positions of the parts relatively to the needle 26, to suit varying binding requirements. I

' Having thus set forth tlie nature of the invention, what I claim herein is 1. In a binder, a base adapted to be adjustably secured to a sewing machine clothplate, opposed binding guides having supports independently slidably adjustable with respect to said base, unitary means for securing said guides to said bas in adjusted position, an independent guide and gage means adjustable toward and from said guides, and means for securing the latter, said means being separate from the means for securing the binding guides. r

2. In a binder, a base, means for adjusta-bly securing said vbase to a sewing machine cloth-plate,,opposed channels formed in the base, a binding guide having a support slidable in one of said channels, a second binding guide having a slotted-support slidable in the other channel, said base having aslot' in alinement with the slot in the support, a clamp-screw passing through said slots and said base, unitary means threaded into said first support, a guide and gage cooperating with said first-mentioned guides and means for independently adjusting it on the base. i

3. In a binder, a base, opposed binding guides slidably secured on opposite sides of for'securing said guides, a guide and gage interposed between said guides and having an offset support, and means for adjustably securing said support to the base- 1 V j I 4t. Ina binder, a base, apair of relatively inclinedbinding guides adjustable thereon and having opposed inturned lips terminating short'of their proximate ends, one of said guides having a guide-flange extending therefrom beyond its in-turned lip, and an inner opposed gage and guide disposed between said first guides.

5. In a binder, a base, a pair of relatively inclined separated binding guides having inturned folding lips terminating short of the discharge end of the binder, an edge flange on one of said guides" between its said dischargeend to guide the binding strip, and an inner opposed workgage and guide lip and between said first guides and having a guide extension projecting beyond the discharge end of the binder.

6. In a binder, a base, a pair of relatively inclined binding and folding guides independently adjustable on said base, and a work-gage disposed between said guides and independentlyadjustable'on said base, said gage extending beyond said guides and having notched portions forming bearings for said guides. I r

V 7. In a binder, a base, opposed binding guides adj ustably secured to said base, unitary means for securing both said-guides to the. base, a guide and gage interposed between said guides and having a support, and

,means independent of said first means for adjustably securing saidsupportto the base.

In testimony whereof I have signed myname to this specification.
